Anti-Resonance
SW2-#1 should be on for the anti-resonance circuit to be
enabled. Normally, you will want anti-resonance to be en-
abled; therefore, this switch should be on. If you are using
pulse placement for positioning, you may need to disable anti-
resonance. You can disable anti-resonance by turning SW2-
#1
off.
Drive Resolution
Set DIP switches SW2-#2 — SW2-#5 for drive resolution.
There are sixteen settings, which range from 200 to 50,800
steps per revolution. The default setting is 25,000 steps per
revolution.
Waveform
Set SW2-#6 — SW2-#8 to select a current waveform. There
are six choices: one is a pure sine wave; the others reduce the
current waveform’s 3rd harmonic by 2%, 4%, 6%, 8% and
10%. In most cases, the default setting (
all three switches
on = -4% 3rd harmonic ) provides the best performance. For
further information about selecting a waveform, see Adjusting
Motor Current Waveforms in Chapter 3 .
Automatic Standby
SW3-#1 and SW3-#2 should be on if you do not use automatic
standby (this is the default position). If you use an indexer
and encoder for position maintenance, we recommend that
you do not use automatic standby.
The automatic standby function allows the motor to cool when
it is not commanded to move. Automatic standby reduces
motor current (by 25%, 50%, or 75%) if the drive does not
receive a step pulse for one second. Full current is restored
upon the first step pulse that the drive receives.
Be aware
that reduced current results in reduced holding torque.
Automatic Test
Set SW3-#3 to the off position to select the automatic test
function. The automatic test turns the motor shaft slightly
less than six revolutions in an alternating mode at 1 rps.
Automatic standby and drive resolution settings are disabled
when you use the automatic test.
The default position for SW3-#3 is on , which disables the
automatic test function.
